Examples of QueryByCriteria

ojb.broker.query.QueryByCriteria
org.apache.ojb.broker.query.QueryByCriteria
represents a search by criteria. "find all articles where article.price > 100" could be represented as: Criteria crit = new Criteria(); crit.addGreaterThan("price", new Double(100)); Query qry = new QueryByCriteria(Article.class, crit); The PersistenceBroker can retrieve Objects by Queries as follows: PersistenceBroker broker = PersistenceBrokerFactory.createPersistenceBroker(); Collection col = broker.getCollectionByQuery(qry); Creation date: (24.01.2001 21:45:46) @author Thomas Mahler @version $Id: QueryByCriteria.java,v 1.26.2.4 2005/12/21 22:27:09 tomdz Exp $
